To all whom t mag/concern j; x Be it known that l, JOHN lViLLiAM Wann@ ER, aV subjectV of the .King` of' Great Britain Sand Ireland, residing'at 8 Russell' Street,

Batley, thejcounty oii-'Yorln' llngland,V have inventednew and useful Improvements fin Movable 'Backs for ApronFeeders, o-which i i the following is a specification. f

Figs. 3, 4, fand 6 are separate detail views vand illustrate'a modification in themeans `for holding the movable board back; or for 'permitting its advance, etc.

My improvements relateY to that class of 'automatic Vfeeder"which has a forward inclined'v spiked lattice oriningxthe `front of the hopper or receptacle, and a movable hack or board forming one'wall or the back of ythe hopper vor receptacle; Generally,'s uch spiked lattice is-given considerable inclination andthe 'ulcruinyo-r Vpivotal point of the-movable backV orfboard vhas'beeninfclose proximity to theloiver iront extremity 'of the said-inclinedspiked lattice. Thus," at'the bottoni-of the f-liopp'er, and intermediate of the lattice and the Inov-v able baclror board, a veryirestricted space.`

' Ahas existed which is in section'in the nature "of anacute'angle. fThis space' may be fully;V

movable back, pivotal supports therefor', movable weights, connections between the movable back and thev movable weights, i

weight boxes, lever catcheswon the weight boxes, and means for cutting out partrof the weight as the back moves inwards andthe hopper empties for the purposes set forth.

Y 3. In automatic feeding machines, afmovl able back, weights to act on the back, guides for the weights, connections between r the movable back an'd .said .weights-and catches pivoted on the sides of the. hopper;A 50V i In testimony whereof I have signed 'myv i once proper feeding hascommenced.
